Tłumaczenie - Włoski-Angielski - [di] vivere la vita

You are right, Ligia Cruz, it doesnt make any sense when featured that way, I hope the validator will edit, and separate "di" and "of" from the rest of the text, for instance using a stuff like that : "[..]", because "vivere la vita" is translated the rigtht way, but no one can say exactly the meaning of "di" without context, could be, as you translated, "of", could be "to", or could be translated by nothing, just by "living life"...

By the way, I've done it myself, because there's no reason for you to be refused this translation because of a lack of context.

Sono contento di vivere la vita

J'éspère que ça te peut aider, vu que tu n'es pas sûr si mettre la "of" ou le "to"
